The bigscreen beyond used 1 inch displays so this could be useful for getting much higher resolutions in a smaller form factor. I don't think my Index displays are even as big as 4 inches so I guess that explains why all the super high res headsets are so huge.

Edit: my index screens are under 3", just did a lens swap so I have the old eye tubes handy

There are many considerations like FOV would be better with a bigger screen, I think 4" would probably be the max, but still that's only at 2k ppi, there'¨s a looong way to 127K. Even with a 4k ppi screen you can do 8k view with just 2".
